"Parenthood" star Dax Shepard and former teen shamus Kristen Bell ("Veronica Mars"), who got engaged nearly three years ago, are expecting their first child together, their rep tells People.com.

While promoting their action comedy "Hit and Run" this summer, they told reporters that they expected to have children before walking down the aisle, because they won't marry until California legalizes same-sex marriage.

Meanwhile, Beverley Mitchell, the former "7th Heaven" star, tells People that she and husband Michael Cameron will welcome their first child in April. “I was like, ‘No, it can’t be that,’” says Mitchell. “I took seven pregnancy tests. I went to the doctor and had two more tests and they were like, ‘Bev, usually when the first one comes out positive, the rest of them will all say the same thing."
